Shinji Senoo has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8404914
    Abstract: The invention provides an efficient process for producing alkylated aromatic compounds such as cumene in a compact reactor. The invention also provides a process for producing phenol which includes a step of producing cumene by the above process. The process for producing alkylated aromatic compounds of the invention includes feeding raw materials including an aromatic compound and an alcohol in a gas-liquid downward concurrent flow mode to a fixed-bed reactor packed with a solid acid catalyst thereby to produce an alkylated aromatic compound, wherein the raw materials are fed to the reactor in a stream of a gas, and the reaction gas flow rate defined by the equation below is not less than 0.05 at an entrance of a solid acid catalyst layer: ?g·ug·[?air·?water/(?g·?l)]1/2(kgm?2s?1).

  • Patent number: 8283504
    Abstract: The invention provides processes for producing 2-propanol with higher purity than heretofore possible while suppressing the by-production of impurities. A process of the invention produces 2-propanol by reacting acetone with hydrogen in the presence of a hydrogenation catalyst, wherein the process includes reacting a raw material mixture containing water and acetone, with hydrogen in the presence of a hydrogenation catalyst, and the raw material mixture contains water at 1.2 to 4.0 wt % based on 100 wt % of the total of the water and the acetone.

  • Patent number: 8273932
    Abstract: The process for producing alkylated aromatic compounds includes feeding raw materials including an aromatic compound, a ketone and hydrogen in a gas-liquid downward concurrent flow mode to a fixed-bed reactor packed with a catalyst thereby to produce an alkylated aromatic compound, wherein the catalyst includes a solid acid component and a metal component, the catalyst is loaded in the fixed-bed reactor such that the catalyst forms a catalyst layer, and the reaction gas flow rate defined by Equation (1) below is not less than 0.05 at an entrance of a layer containing the solid acid: ?g·ug·[?air·?water/(?g·?l)]1/2 (kgm?2s?1).

  • Publication number: 20110092745
    Abstract: The invention provides an efficient process for producing alkylated aromatic compounds by directly reacting an aromatic compound with a ketone and hydrogen in a compact reactor. The invention further provides a process for producing phenol which includes a step of producing cumene by the above alkylation process. The process for producing alkylated aromatic compounds includes feeding raw materials including an aromatic compound, a ketone and hydrogen in a gas-liquid downward concurrent flow mode to a fixed-bed reactor packed with a catalyst thereby to produce an alkylated aromatic compound, wherein the catalyst includes a solid acid component and a metal component, the catalyst is loaded in the fixed-bed reactor such that the catalyst forms a catalyst layer, and the reaction gas flow rate defined by Equation (1) below is not less than 0.
